Cannabis and schizophrenia During recent, years, controversial discussions have resumed regarding whether cannabis consumption might increase the risk of drogues et effects schizophrenic symptoms. Andreasson et al 24 referred to the first, evidence that cannabis may be a causal risk factor for later schizophrenia.
Several recent studies have investigated the risk factor of cannabis use for future psychotic symptoms, and research in this field has provided a growing body of evidence drogues et effects the use of cannabis may be associated with increased risks of psychosis and psychotic symptoms.
In particular, heavy cannabis use may accelerate or exacerbate psychotic symptoms in vulnerable individuals. In recent, years, advances in the understanding of brain cannabinoid receptor function and the association between cannabinoid compounds and psychosis have been made.
Data from a double-blind, randomized, and counterbalanced study indicate that intravenously administered dcltatetrahydrocannabinol delta 9-THC produces a wide range of drogues et effects symptoms, behaviors, and cognitive impairments in healthy individuals, resembling several aspects of endogenous psychoses.
At the age of 11 psychotic symptoms were assessed from self reports. Following the same procedure at, 15 to 18 years, drogues et effects subjects were examined with regard to their cannabis use.
Substance abuse in patients with schizophrenia
At the age of 26, psychiatric symptoms were evaluated using a standardized interview schedule to obtain diagnostic criteria according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition DSM-IV.
Another New Zealand longitudinal study 26 investigated a cohort of people born in mid At ages 18, 21, and 25 years, sample members were administered a comprehensive mental health interview designed to assess a number of aspects of mental health and psychosocial adjustment.
In addition, at each assessment, subjects were questioned about their cannabis use. The findings of this study, based on a sample of participants, suggest, that daily users of cannabis had rates of psychotic symptoms that, were between 1.
However, critical comments do not support, these results, but emphasize that, the findings of Fergusson et al, 26 based on just 10 items from the Symptom Checklist, would raise more questions than they would be able to answer. Marijuana smokers may have beliefs that, are drogues et effects, from the mainstream, and thus could be suspicious of others.
An important limitation, however, includes the fact that prospective studies are based on self-reported measurements of cannabis use.

Overall, cannabis docs not, seem to represent a sufficient cause for the development of schizophrenia. However, even though the majority drogues et effects young people who use cannabis in adolescence do so without experiencing a harmful outcome, there are consistent findings that cannabis use does indeed increase the risk for schizophrenia and other psychotic disorders in vulnerable people.
Cocaine yields to a blockade of presynaptic dopamine reuptake, producing a large increase in synaptic dopamine. This effect is blocked through dopamine receptor antagonists, and should discourage abuse.
However, this may be counterbalanced through other factors, drogues et effects negative symptoms and depressed mood.

drogues et effects Based on the self-medication hypothesis, schizophrenic patients may use cocaine to counteract, extrapyramidal side effects occurring as a result of antipsychotic drug treatment.
Furthermore, cocaine may be used in order to overcome a defect in dopamine-mediated reward circuits.
An important, limitation, however, involves the small sample size of 24 patients. A recent pilot study, however, provided some evidence that treatment with aripiprazole, a partial dopamine agonist with high affinity for both dopamine D2 and D3 receptors, might, possibly lower both the desire for and the use of cocaine in these patients.
Anyway, these findings need a cautious interpretation with respect to the small sample size of 10 subjects, and should be reassessed anyway using drogues et effects double-blind, randomized comparison study design.
Intervention and aim of treatment Since schizophrenia and substance misuse have been determined to be closely interdependent, a dual diagnosis - treatment of schizophrenia and drug abuse is needed.
Currently, research is focusing on a range of psychological strategies such as family intervention, skills training, cognitive therapy, or development of substance refusal. To date, there is a growing body of evidence that motivational enhancement interventions, which tend to alter drug use and refine skills, may be a feasible first-line intervention for substance abuse in early psychosis.
However, the main focus of treatment for these patients consists in stabilization of psychotic symptoms, hostility, and agitation.
